Notch is able to treat, animate, augment and export VR / 360 videos all in one tool with completely real-time editing and in-headset preview - an offering not available in any other package.
Key to creating VR / 360 content is the ability to create your content using a VR headset, before rendering out to VR / 360 video.
There are various terms marketing terms that exist for VR / 360 Videos, but the two most common are:
360 Videos : Monoscopic videos that allow the user to look around, either in a desktop browser, Google Cardboard or a headset. VR Videos : Stereoscopic videos, where a 360 view is rendered for each eye and composited (top & bottom) into a single video. These are much more immersive experiences on Cardboard or VR headsets.
The Notch workflow for both 360 and VR videos is the same. The only difference is that for stereoscopic rendering is enabled for VR Videos.
VR / 360 is enabled by a single additional node - the VR 360 Camera node. This camera can be placed anywhere in the scene, where it looks in all directions simultaneously with a spherical wrap.
Not all Post-FX nodes are currently compatible with the VR 360 Camera. Development is continuing to bring compatibility for all relevant effects. If your immediate project needs a specific effect supported, please contact us directly.
It’s not necessary to know how the background process works, but for the curious…
The VR 360 Camera utilises cuboid multi-view rendering. For each eye, Notch renders the scene six times in the six directions of a cuboid view. The renders are then applied to a surrounding cube which seamlessly stitches the view back together, before being output to the 360 spherical map texture.
The creation of content for VR / 360 videos is best achieved by creating your content using the VR Headset Camera and then using the VR 360 Camera to export to video.
See Using Headset VR for details on how to create using a headset.
Tuning the interocular and convergence distance is critical to ensuring a comfortable and compelling 3D experience in VR Videos. You can read further about it in Understanding Comfortable Stereography - Affonso Beato
It is possible to preview the output of the VR / 360 video in the headset before exporting. This is useful for checking resolution selection and Interocular & Convergence Distances.
Video specifications for 360 players are fairly strict and you need to research your target. YouTube 360 Specifications
To export to a VR 360 video:
The VR 360 Camera can be used as a source for POV mappings, either internally in Notch or with media servers that support spherical maps.
